ClimaHtech CEMENT



The cement industry

Cement contributes about 8% of global annual emissions and is a critical material we need to build infrastructure including roads, hospitals, and even wind turbines.

Intrinsic emissions from cement production primarily result from the breakdown of limestone into clinker and the subsequent heating of clinker to produce cement. Calcination process emits 60% of total production emissions, with 40% coming directly
from burning fossil fuels.

Industry will require GW scale of renewables to meet 2050 targets, with emissions needing to fall by at least 16% by 2030.


ClimaHtech technology

ClimaHtech can complement existing sustainable changes to the cement sector such as to accelerate the decarbonisation of cement production to help create lower carbon cement products.

A study showed how to decarbonise Mannok Cement operations by 18%

A combined team of CATAGEN and Mannok engineers have identified several pathways to help decarbonise cement production at Mannok’s Cement Plant in Ballyconnell through a techno-economic study which produces one million tonnes of cement annually.

  • The study has determined that the use of the HGEN technology could reduce annual carbon emissions by 7 percent.
  • Biohydrogen generation from waste biomass can generate larger volumes of hydrogen with less renewable energy required compared to electrolytic hydrogen generation. The use of BIOHGEN technology could reduce the carbon intensity of cement produced at this site by a further 18 percent by reducing fossil fuel use.

We are very excited to be working with the CATAGEN team, who have demonstrated a deep level of technical ability and competency during the feasibility work. I have no doubt that Mannok will derive significant value from the work already completed, with many new opportunities for collaboration now presenting that we would not have considered before. Achieving Net Zero is now the primary goal for our business and I expect CATAGEN will play a significant role in our achieving that goal, which we expect will have major benefits for the sector overall.
